FIELD

This technology relates to methods and devices for analyzing quality of experience for consumers of streaming video.

BACKGROUND

Application management computing devices can accelerate and optimize network traffic communicated between server devices and client devices in order to improve the user experience. Application management computing devices can also perform other functions on network traffic, such as load balancing the network traffic to server devices and/or implementing firewalls or other security functionality for the network, for example.

Network traffic handled by application management computing devices includes an increasing amount of streaming video content of various types including HyperText Transfer Protocol (HTTP) Live Streaming (HLS), Dynamic Adaptive Streaming over HTTP (DASH), or Adaptive Bitrate Streaming (ABS), for example. Video segments for streaming video content are generally retrieved using hierarchically structured playlists, whereby a master playlist file stores network addresses of a secondary playlist file which stores network addresses of the video segments. A master playlist file can include network addresses of a plurality of secondary playlist files, each associated with a different bit rate.

Accordingly, upon receipt of the master playlist file, an application, such as a video player executing on a client device, can decide which bit rate is currently most appropriate, or is likely to result in an optimal experience for the user, and request one of the secondary playlist files using the corresponding network address indicated in the master playlist file. Over time, and depending on network characteristics or observations, the application may request various video segments corresponding to different bit rates from several of the secondary playlist files using the corresponding network addresses of the segments indicated in the secondary playlist files.

Hosts or providers of such streaming video content are often interested in the quality of experience (QOE) for users or viewers of the content so that changes can be made to improve poor QOE. Currently, methods for scoring QOE are relatively ineffective, qualitative, and therefore relatively inaccurate. Additionally, current methods for QOE scoring generally require user interaction, such as through surveys or questionnaires.

While some QOE scoring methods have been developed for traditional progressive video streaming that do not require user interaction, these methods are not effective for certain types of streaming video content. For example, these methods have reduced effectiveness for content of the HLS type because multiple connections may be used by a client device to obtain a plurality of segments for a video. In these types of streaming video content, insufficient data is available on a per-connection basis to generate an effective or accurate QOE score for the video.

DETAILED DESCRIPTION

Referring to FIG. 1, a block diagram of an exemplary network environment 10 including an exemplary application management computing device 12 is illustrated. In this example, the application management computing device 12 is coupled to a plurality of client devices 14(1)-14(n) through a local area network (LAN) 16 and a wide area network (WAN) 18 and a plurality of server devices 20(1)-20(n) through another LAN 22, although the application management computing device 12, client devices 14(1)-14(n), and server devices 20(1)-20(n) may be coupled together via other topologies. The network environment 10 may include other network devices such as one or more routers and/or switches, for example, that are well known in the art and will not therefore be described herein. This technology provides a number of advantages including methods, non-transitory computer readable media, and devices that facilitate improved quality of experience (QOE) analysis for streaming video across various connections associated with a user session.

Referring to FIGS. 1-2, the application management computing device 12 may perform any number of functions in addition to QOE analysis, such as optionally optimizing, securing, and/or load balancing the network traffic exchanged between the client devices 14(1)-14(n) and the server devices 20(1)-20(n), for example. In this particular example, the application management computing device 12 includes a processor(s) 24, a memory 26, and a communication interface 28 which are coupled together by a bus 30 or other communication link, although the application management computing device 12 may include other types and numbers of elements in other configurations.

The processor(s) 24 of the application management computing device 12 may execute programmed instructions for any number of the functions identified above and/or described herein for analyzing QOE for streaming video content and, optionally, managing network traffic and/or optimizing service of content requests, for example. The processor(s) 24 of the application management computing device 12 may include one or more central processing units and/or general purpose processors with one or more processing cores, for example.

The memory 26 of the application management computing device 12 stores these programmed instructions for one or more aspects of the present technology as described and illustrated herein, although some or all of the programmed instructions could be stored and executed elsewhere. A variety of different types of memory storage devices, such as random access memory (RAM), read only memory (ROM), hard disk drives, solid state drives, or other computer readable media which is read from and written to by a magnetic, optical, or other reading and writing system that is coupled to the processor(s) 24, can be used for the memory 26.

In this example, the memory 26 further includes a session database 32. The session database 32 is used by the application management computing device 12 to maintain persistency across a plurality of connections associated with a session to facilitate more effective QOE monitoring and analysis, as described and illustrated in more detail later.

The communication interface 28 operatively couples and communicates between the application management computing device 12, client devices 14(1)-14(n), and server devices 20(1)-20(n), which are all coupled together by the LANs 16 and 22 and WAN 18, although other types and numbers of communication networks or systems with other types and numbers of connections and configurations to other devices and elements. By way of example only, the LANs 16 and 22 and WAN 18 can use TCP/IP over Ethernet and industry-standard protocols, including NFS, CIFS, SOAP, XML, LDAP, and SNMP, although other types and numbers of communication networks, can be used.

The LANs 16 and 22 in this example may employ any suitable interface mechanisms and network communication technologies including, for example, teletraffic in any suitable form (e.g., voice, modem, and the like), Public Switched Telephone Network (PSTNs), Ethernet-based Packet Data Networks (PDNs), combinations thereof, and the like. The WAN 18 may comprise any wide area network (e.g., Internet), although any other type of traffic network topology may be used.

Each of the client devices 14(1)-14(n) and server devices 20(1)-20(n) includes a processor, a memory, and a communication interface, which are coupled together by a bus or other communication link, although other numbers and types of network devices could be used. Each of the client devices 14(1)-14(n) may further include an input device or a display device and may run interface applications, such as Web browsers or video player applications or plug-ins, that may provide an interface to make requests for and receive content including streaming video content hosted by the server devices 20(1)-20(n) via the LANs 16 and 22 and/or WAN 18.

The server devices 20(1)-20(n) may provide content, including streaming video content, or other network resources in response to requests directed toward applications hosted by the server devices 20(1)-20(n) from the client devices 14(1)-14(n) via the LANs 16 and 22 and/or the WAN 18 according to the HTTP-based application RFC protocol or the CIFS or NFS protocol, for example. The server devices 20(1)-20(n) may be hardware or software or may represent a system with multiple server devices in a server device pool, which may include internal or external networks. Various network processing applications, such as CIFS applications, NFS applications, HTTP Web Server device applications, and/or FTP applications, may be operating on the server devices and transmitting data (e.g., media content, video segments, files, and/or web pages) in response to requests from the client devices 14(1)-14(n).

Although the exemplary network environment 10 with the application management computing device 12, client devices 14(1)-14(n), server devices 20(1)-20(n), LANs 16 and 22, and WAN 18 are described and illustrated herein, other types and numbers of systems, devices, components, and elements in other topologies can be used. It is to be understood that the systems of the examples described herein are for exemplary purposes, as many variations of the specific hardware and software used to implement the examples are possible, as will be appreciated by those skilled in the relevant art(s).

In addition, two or more computing systems or devices can be substituted for any one of the systems or devices in any example. Accordingly, principles and advantages of distributed processing, such as redundancy and replication also can be implemented, as desired, to increase the robustness and performance of the devices and systems of the examples. The examples may also be implemented on computer system(s) that extend across any suitable network using any suitable interface mechanisms and traffic technologies, including by way of example only teletraffic in any suitable form (e.g., voice and modem), wireless traffic media, wireless traffic networks, cellular traffic networks, G3 traffic networks, Public Switched Telephone Network (PSTNs), Packet Data Networks (PDNs), the Internet, intranets, and combinations thereof.

The examples may also be embodied as one or more non-transitory computer readable media having instructions stored thereon for one or more aspects of the present technology as described and illustrated by way of the examples herein, as described herein, which when executed by a processor, cause the processor to carry out the steps necessary to implement the methods of the examples, as described and illustrated herein.

Exemplary methods for monitoring streaming video content quality of experience (QOE) will now be described with reference to FIGS. 1-5. Referring more specifically to FIG. 3, a method for analyzing a QOE for a streaming video across connections with one of the client devices 14(1)-14(n) is illustrated. In step 300 in this example, the application management computing device 12 receives a request for content from one of the client devices 14(1)-14(n) via the LAN 16 and the WAN 18. The request can be an HTTP request for content stored by one of the server devices 20(1)-20(n), for example.

In step 302, the application management computing device 12 determines whether the requested content is a segment of streaming video. For example, the application management computing device 12 can determine whether the request is for a segment of content having a type comprising HyperText Transfer Protocol (HTTP) Live Streaming (HLS), Dynamic Adaptive Streaming over HTTP (DASH), or Adaptive Bitrate Streaming (ABS), although the requested content can be a segment of streaming video of another type. If the application management computing device 12 determines that the requested content is not a segment of streaming video, then the No branch is taken back to step 300 and another request for content is received. Optionally, the request is also processed by the application management computing device 12, such as by retrieving the content from one of the server devices 20(1)-20(n) or performing another action, for example.

However, if the application management computing device 12 determines in step 302 that the requested content is a segment of a streaming video, then the Yes branch is taken to step 304. In step 304, the application management computing device 12 retrieves the segment from one of the server devices 20(1)-20(n) and extracts a session identifier from an HTTP header of the response from the one of the server devices 20(1)-20(n) that includes the requested segment. In one example, the session identifier can be extracted from an HTTP header of the request received in step 300 and maintained by the application management computing device 12 until the HTTP response with the segment is retrieved. In another example, the requested content is a segment of live streaming video content of an HLS type and the session identifier is extracted from an X-PLAYBACK-SESSION-ID HTTP header, although the segment can be of another type of streaming video and the session identifier can be extracted from another HTTP header.

In step 306, the application management computing device 12 parses the retrieved segment to obtain static parameters associated with the segment, determines dynamic parameters associated with the streaming video content, and/or determines a segment QOE score for the segment, although other types and/or numbers of operations in other combinations could be performed. Optionally, other information may also be obtained in step 306, such as device capabilities of the requesting one of the client devices 14(1)-14(n) by way of example only. Also optionally, the additional information could be retrieved from a third party database using a user agent indicated in a header of the HTTP request or response, for example. In one example, the static parameters may include one or more of a nominal bit rate, a frame rate, a frame width, or a frame height, although other types and/or numbers of static parameters can also be obtained.

The dynamic parameters can include one or more of an actual bit rate, a freeze duration, or a freeze frequency, and can be generated based on an updating of previously stored information associated with segments of the video requested during the session, although other types and/or numbers of dynamic parameters can also be obtained as described and illustrated in more detail later.

The QOE score for the segment can be determined based on at least one or more of the static and/or dynamic parameters, which may optionally have a weighting factor applied, although the QOE score can be generated based on other types and/or numbers of parameters or other information. One exemplary method of determining a QOE score is disclosed in U.S. Provisional Patent Application Ser. No. 62/078,685, filed Nov. 12, 2014, which is hereby incorporated by reference in its entirety.

In step 308, the application management computing device 12 stores at least the static and/or dynamic parameters, segment QOE score, and an indication of the segment, in a record of the session database 32 associated with the session identifier extracted in step 304. Additionally, the application management computing device 12 can optionally determine whether a record associated with the session identifier already exists, which it can update. Alternatively, the application management computing device 12 can determine whether the segment is the first segment of the streaming video requested by the one of the client devices 14(1)-14(n) within the current session, in which case the application management computing device 12 can insert a new record associated with the session identifier into the session database 32.

Referring more specifically to FIG. 4, an exemplary session database 32 is illustrated. In this particular example, the session database 32 includes a record for each unique session identifier that is consistent across any number of connections via which segments of the streaming video are obtained by the one of the client devices 14(1)-14(n). Within each record of the session database 32 in this example, an indication of each of the requested segments is stored along with the associated obtained static parameters and generated dynamic parameters and segment QOE score, although other information can also be included in one or more of the records of the session database 32. Accordingly, by using the session database 32, the application management computing device 12 can determine the dynamic parameters for a segment in step 306 based on dynamic parameters or other stored information associated with one or more other segments of the streaming video previously requested and retrieved by the one of the client devices 14(1)-14(n).

Referring back to FIG. 3, in step 310, the application management computing device 12 sends the retrieved segment to the requesting one of the client devices 14(1)-14(n). In step 312, the application management computing device 12 determines whether the segment represents the end of the associated streaming video, such as by comparing a number of the segment with a previously retrieved playlist or manifest file, for example. If the application management computing device 12 determines that the end of the video has not been reached, then the No branch is taken to step 314.

In step 314, the application management computing device 12 determines whether a request for another segment of the video is received from the one of the client devices 14(1)-14(n). The additional request can be received via a different connection between the one of the client devices 14(1)-14(n) and the application management computing device 12 than the connection via which the request for the segment was received in step 300, although the connections can also be the same. If the application management computing device 12 determines that a request for another segment of the streaming video is received, then the Yes branch is taken back to step 304, and steps 304-314 may be repeated in a subsequent iteration.

However, if the application management computing device 12 determines in step 314 that a request for another segment of the video has not been received from the one of the client devices 14(1)-14(n), then the No branch is taken to optional step 316. In step 316, the application management computing device 12 determines whether a threshold time period has elapsed since the one of the client devices 14(1)-14(n) has requested a segment of the streaming video. The threshold time period can be established by an administrator of the application management computing device 12, for example. Exceeding the threshold in this example indicates that the user has stopped playing the video even though the end of the video has not been reached. Accordingly, in this example, the application management computing device 12 can maintain a time at which each segment of the streaming video is requested by the one of the client devices 14(1)-14(n), the last of which can be compared to a current time by the application management computing device 12 to determine whether the threshold time period has elapsed.

If the application management computing device 12 determines in step 316 that the threshold time period has not elapsed, then the No branch is taken back to step 314 and the application management computing device 12 essentially waits for a request for another segment of the streaming video to be received or the threshold time period to be exceeded. However, if the application management computing device 12 determines in step 316 that the threshold time period has elapsed, and the Yes branch is taken from step 316, or if the application management computing device 12 determines in step 312 that the end of the video has been reached and the Yes branch is taken from step 312, the application management computing device proceeds to step 318.

In step 318, the application management computing device 12 determines a video QOE score for the video based on each of the segment QOE scores determined in step 316, and stored in the record associated with the session identifier in step 308, and outputs the video QOE score, although other methods of determining the video QOE score can also be used. Optionally, the video QOE score can be output by the application management computing device 12 to a host or provider of the streaming video content to thereby provide the host with information regarding the quality of the service being experienced by the user of the one of the client devices 14(1)-14(n) with respect to the streaming video.

In step 320, the application management computing device 12 optionally removes the record associated with the session identifier from the session database 32. Accordingly, in this example, once the video QOE score is output, the record does not need to be maintained in the session database 32 and can be removed to make space available for additional records. Subsequent to removing the record, or in parallel with any of the steps illustrated in FIG. 3, the application management computing device 12 proceeds back to step 300 and receives another request for content from the one of the client devices 14(1)-14(n) or another of the client devices 14(1)-14(n).

Referring more specifically to FIG. 5, an exemplary timing diagram of an exemplary method for analyzing QOE for a streaming video across connections with the client devices 14 is illustrated. In step 500 in this example, the client device 14 sends a request for content to the application management computing device 12. In step 502, the application management computing device 12 determines whether the requested content is a segment of a streaming video. If the application management computing device 12 determines that the requested content is not a segment of a streaming video, then the No branch is taken back to step 500 and the client device 14 sends another request for content.

However, if the application management computing device 12 determines in step 502 that the requested content is a segment of a streaming video, then the Yes branch is taken and, in step 504, the application management computing device 12 requests the segment from server device 20. In step 506, the server device 20 responds by sending the segment to the application management computing device 12.

In step 508, the application management computing device 12 extracts a session identifier from a header of the received response, generates one or more static parameters by parsing the payload or segment included in the response, generates one or more dynamic parameters for the segment, and generates a segment QOE score for the segment based on the static and dynamic parameters. Optionally, the session identifier can be extracted from a header included in the request received in step 500. Additionally, the application management computing device 12 stores the static and dynamic parameters, segment QOE score, and optionally an indication of the segment in a record of a session database 32 associated with the session identifier.

In step 510, the application management computing device 12 sends the requested segment to the client device 14. In step 512, the application management computing device 12 determines whether the end of the streaming video has been reached. If the application management computing device 12 determines that the end of the streaming video has not been reached, then the No branch is taken and the application management computing device 12 essentially waits for another request for another segment of the streaming video to be received. Upon receipt of another request in step 514, the application management computing device 12 proceeds back to step 504 and steps 504-512 are repeated.

However, if the application management computing device 12 determines in step 512 that the end of the video has been reached, then the Yes branch is taken to step 516. In step 516, the application management computing device 12 generates and outputs a video QOE score for the streaming video. The video QOE score can be generated based on the segment QOE scores for each of the segments, as previously determined and stored in the session database 32, as described and illustrated in more detail earlier. In step 518, the application management computing device 12 removes the record associated with the session identifier from the session database 32.

Accordingly, with this technology, a more effective QOE score can be generated for analyzing user experience with streaming video content without any user intervention. By using a session identifier and a session database, persistency can be maintained even though many connections may be utilized to obtain any number of segments of a streaming video. Accordingly, a segment QOE score can advantageously be determined using static and dynamic parameters for an increased number of segments for streaming video content, resulting in a more effective video QOE score and associated quality analysis of the streaming video content.

Having thus described the basic concept of this technology, it will be rather apparent to those skilled in the art that the foregoing detailed disclosure is intended to be presented by way of example only, and is not limiting.
